WHEESLBARROW.

SPECIFICATION forming part of Letters Patent No. 273,225, dated February27, 1883.

' Application filed January 5, 1883. (No model.) I

To all whom it may concern Be it known that I, WILLIAM GLARK,ttcitizenof the United States of America, residing at Baltimore, in the State ofMaryland, have invented certain new and useful Improvements inWheelbarrows, of which the following is a specification, reference beinghad therein to the accompanying drawings.

Myiuventlon relates to an improvement in lo wheelbarrows, and first willbe described, and

then designated in the claims.

In the drawings hereto annexed, Figure l is a side View of a wheelbarrowwith my improve ment applied. Fig. 2 is a top view. Fig. 3 is a frontend view. Fig.4 is a perspective view of the device. I

The letter A designates the side bars or handles, and B the wheel, of anordinary wheelbarrow.

O designates my improved dumping-rocker applied to the ,end of each sidebar. The object of this device is to facilitate the tilting of thebarrow to dump the load, and at the same time to prevent the barrow fromslipping while in the tilted position. The dumping-rockeris a metalplate, d, to project edgewise from the side of the bar, and the outeredge of the rocker is curved or partly circular. Teeth or serrations 0are formed on the curved edge. This 0 construction allows thedesiredrocking movement, and also provides against-any slipping of the rocker.To adapt the rocker for being rigidly secured to the side bar of thebarrow, the rocker-plate dis joined at right angles to 5 asecuring-plate, f. A brace, g, between the two platesdandfmaybee-mployed to strengthen the parts.- The securing-plate has at one edgea flange, h, which projects from the surface opposite that from whichthe rocker-plate projects. This flange is designed to fitagainst I orunder the lower edge of the side bar, while the surface f rests againstthe outer side of said bar. A bolt-hole, '5, is formed in thesecuring-plate, and a bolt, i, passes through said holeandthroughthesidebar. Bythesemeans 5 the rocker may he very firmly attached to the sidebar.

A wheelbarrow thus provided is well adapted for wheeling on a plankwayand dumping, as, when tiltingit for the purpose of dumping, 0 the teethof the rocker may rest on the plank, and thereby have a solidresting-place whereon to rock, and with which the teeth also engage.

In loading and unloading vessels with ore, coal, fertilizers, 850.,where wheelbarrows are employed, it often happens that the barrow, whilein the tilted position, slips, because the end of the side bar on whichthe barrow and load for the time being rest has nothing to preventslipping. From this cause the barrow may be loosened entirely from thegrasp and drop into the hold of a vessel.

Having described my invention, I claim and desire to secure by LettersPatentof the United States 1. A dumping-rocker forwhee1barrows,consisting of a metal plate whose outer edge is providedwith teeth or serrations which form a curve or part circle, as setforth. 7o

2. A Wheelbarrow having at the end of the side bar a dumping-rockerprovided with teeth or serrations, as set forth.

In testimony whereof I affix my signature, in

presence of two witnesses, this 12th day of December, 1882.

WILLIAM CLARK.
